On average, bald eagles were perched 91 % of the time; and perching was the most frequently observed activity (£ < 0.001). Adult eagles perched more often in conifers than cottonwoods, snags, or intertidal debris (£ < 0.001).

Fifty-eight percent of radio-ma~ked adult eagles used 3 watersheds in Glacier Bay from August through January 1991-1993.
